GenTrans Devices

Generator / Transfer Switch Operation      GenTran Type

There are 3 basic operations. The process is the same, whether for test purposes or for actual power failures.

1. Get the generator started without any electrical load.
  1. If necessary, move generator to proper location for operation. (Remove any coverings.)
  2. Connect safety ground wire between ground rod and generator.
  3. Check oil level.  (Low oil level will cause sensor to prevent generator from running.)
  4. For gasoline models, fill tank with gasoline.  Wipe off any spillage.
  5. Plug twist-lock extension cord into generator and weatherproof outlet box.  They only need a small turn (clockwise to lock.)
  6. Pull choke lever for initial start-up.
  7. For electric start units, turn key or push button to start.
  8. Otherwise, pull cord to start engine.
  9. Once motor is started, push choke lever back in to normal position.
  10. Allow motor to run for 5 minutes or so to warm up.
  11. At transfer switch, you can verify that power from generator is functioning by plugging a light into the outlet on the transfer switch.

2. Switch circuits over from the utility feed to the generator feed.
On the transfer switch panel:
  1. Flip individual circuit switches from Utility position to Generator position.  Depending on load, you can switch as many or as few switches as desired.
  2. Monitor the 2 load meters on the panel to see how much power is being used.  Each meter should not exceed ½ the rated (running or constant) rating of the generator.  The 2 meters do not usually register identical amounts.
  3. If the load meters show too much power being used for the generator, or to prevent items from being powered, shut off individual circuit switches.

3. When finished with the test, or utility power is back on:
  1. On transfer switch panel, return all switches to Utility position.
  2. Turn off generator.
  3. Unplug the twist-lock extension cord. .
  4. Disconnect ground wire at generator.
  5. Allow the generator to cool completely before storing.
